- Description: A three-year survey of the ecology of entomopathogenic nematodes (EPN) and entomopathogenic fungi (EPF) was undertaken on soils from citrus orchards of different ages to determine the influence of orchard age on the ecology of entomopathogenic fungi and nematodes. The influence of mulch and irrigation method on the occurrence of EPN and EPF was also determined. Most of the isolates recovered (n = 810) were Beauveria sp. (87.88% of all isolates), followed by Metarhizium sp. (11.87% of all isolates). Only 0.24% of soil samples collected during this study tested positive for EPN. All EPN isolates recovered were Heterorhabditis bacteriophora. No significant differences in EPF occurrence were recorded between orchards under drip and micro-sprinkler irrigation. EPF occurrence was significantly lower (P = 0.016) in orchards covered by mulch (31.85% ± 2.07% occurrence) than in orchards with no covering (38.57% ± 1.57% occurrence). EPF occurrence of 40.33 ± 2.13% was highest in non-bearing orchards, followed by mature orchards (nine years or older) (36.76 ± 2.05% of samples) with the lowest EPF occurrence of 25.30 ± 2.02% reported in juvenile orchards (four to eight years old). Juvenile orchards sustain significantly less EPF than mature and non-bearing orchards because of the combined negative impact of less favourable environmental conditions (lower shade density) and fungicide applications.

- Description: The rapid advancements in technology has seen a growing shift in retail industry trends, with many retailers establishing online shopping platforms. Though online shopping was initially more popular in other parts of the world, it is fast becoming more popular in South Africa. Many South Africans are now starting to feel more comfortable with the experience, convenience and benefits of online shopping and thus it is important for researchers and experts to gain a better understanding of customers’ experiences in this regard. Furthermore, customer service and quality of service in the online shopping space tends to be relatively different to customer service and quality experienced at a traditional retail store. Therefore, understanding customer service and quality of service within the online retail space is also a critical area to be researched. The aim of this study is thus is to assist retailers and managers to better understand customer service quality of online shopping platforms and how these online shopping platforms perform in terms of its reliability, assurance, tangibility, empathy, and responsiveness dimensions of service quality. An empirical study, consisting of a questionnaire was conducted amongst 88 South African males and females from the various generational cohorts who utilise online shopping platforms. Furthermore, the purpose of this study was to evaluate the service quality experiences of customers who make use of online shopping platforms. The key findings indicated that reliability, tangibility and empathy are the key determinants affecting a customer’s intention to purchase from an online shopping platform. Furthermore, recommendations were made to retailers and managers to consistently focus on remaining reliable in terms of delivering goods as promised; accepting returns and offering refunds, as well as maintaining accurate client and product information; consistently striving towards providing exceptional tangible experiences, such as maintaining a visually appealing website that is easy to navigate, safe and secure to conduct transactions and, to always ensure that customer service agents show empathy towards to their customers.

- Description: Many of today’s news headlines are fraught with alarming accounts of fraud and Corruption conducted by business leaders and this study was undertaken to investigate the influence of perceived ethical leadership on employee engagement. The question has arisen whether these unethical actions among business leaders impact the perceptions of employees and whether this affects their engagement with the organisation. There has been an increase in studies on employee engagement, due to the significant positive impact that it has on an organisation and the beneficial outcomes that engaged employees produce. In this study, the research design followed a positivist approach. The research participants consisted of middle managers in the public or private sectors in South Africa. Sampling was done using a non-probability convenience sampling technique. Secondary data was collected using research data from the Nelson Mandela University Library and its online database. Primary research data was collected using self-administered, standardised questionnaires making use of a 5-point Likert scale. Data was interpreted by means of inferential statistics and biographical information. Every precaution was taken to ensure the reliability, validity and trustworthiness of the study. Ethical approval was obtained for the study from the Nelson Mandela University Research Ethics Committee as per the protocols that were in place at the time of the data collection. This study is significant in terms of the upsurge in unethical conduct in the business arena. The primary objective of this research was to determine the influence of perceived ethical leadership (Perceived Leader Integrity) on employee engagement (the factors which constitute engagement are job commitment, job satisfaction and future intentions.). In the findings, a moderate relationship was found between PLI and job commitment and job satisfaction. A negative relationship was established between PLI and future intentions. Therefore, ethical leadership had an influence on employee engagement.

- Description: The construction industry is characterised by the high rate of project failures. Industry professionals consider inconsistent project management practices to be a major cause of these failures. A leading contributor to these inconsistent project management practices is that there is no one project management standard followed in the industry, thereby resulting in different interpretations and applications by project managers. Given the intricate nature of construction projects, correct project management practices and project management maturity are paramount in achieving the overall envisaged project benefits,project success and business profit by organisations. As such, this study arose from the desire to improve the prevailing practices in construction projects, particularly in the Private Healthcare Industry. Against this background, the purpose of this study was to develop a framework that aims to improve the prevailing project management practices in infrastructure projects within the Private Healthcare Industry. This was done through evaluating the appropriate frameworks and theories in construction project management practices, project management maturity, and project success concepts. This then led to determining the correct construction project management practices required for the successful execution of infrastructure projects. To achieve this goal, a comprehensive review of literature was conducted that covered a review of project management practices, benefits, and theories The review of literature concluded with the main study proposition: Project management maturity has an influence on project success.

- Description: With every passing year, there is a decrease in the number of learners pursuing science degrees after completion of grade 12. One of the main reasons for this is the negative attitude that high school learners have towards science learning and science as an entity. The Natural Sciences curriculum suggests the use of local knowledge to introduce the usefulness and the relatability of science to learners. This study is an intervention that seeks to ascertain the influence that local knowledge has on the attitudes of grade 8/9 learners when integrated into their chemistry hands-on practical activities. The study was informed by Vygotsky’s social constructivist theory and Wenger’s community of practice theory. Grade 8/9 learners from four high school science clubs did three local knowledge integrated experiments based on acids and bases. The learners completed pre- and post- surveys and were interviewed about their experiences. Volunteers at the science clubs were also interviewed. Excel was used to deductively analyse quantitative data. On the other hand, an inductive-deductive thematic approach was used to analyse the qualitative data. The findings of the study showed a divergence of qualitative and quantitative methods. The quantitative data showed that there was a slight decrease (but not statistically significant) in the attitude of the learners after engaging in chemistry hands-on practical activities into which local knowledge had been integrated. On the other hand, the qualitative data showed that there was a positive shift in the learners’ attitudes after they had been engaged in the chemistry hands-on practical activities. Additionally, the findings of the study revealed that the integration of local knowledge promotes conceptual understanding and improves the performance of the learners. This study thus recommends that local knowledge should be integrated into the grade 8 and 9 learners’ curriculum to enrich and promote contextualized science for learners. Additionally, the integration of local knowledge would promote conceptual understanding and spark interest and motivation in learners to pursue science-related careers.

- Description: Worldwide, states that had incorporated international standards of arbitration or drew influence from them, thrived in providing effective and efficient resolution of international commercial disputes. However, since 1965, there had been little to no increase in resolving international commercial disputes between private parties in South Africa, either through the court or arbitration. As a result, private parties were drawn to arbitrating in states that had incorporated these international standards and conformed to the aim of unifying arbitral regulation. This study aims to determine what South Africa’s response was in dealing with international commercial disputes and the development of arbitration as an appropriate dispute resolution mechanism. Based on the premise that arbitration is regarded as a popular dispute resolution mechanism when it comes to international trade transactions globally, this study will unpack why arbitration in South Africa did not reflect this premise. A thorough analysis of how international arbitration and its regulation developed globally will be conducted to show at what point uniform regulation came about. The results will indicate in what ways South Africa’s regulatory framework was insufficient to deal with international arbitration and will show how it took a considerable amount of time to regulate arbitration appropriately. Upon regulating international arbitration in 2017, the study will show other ways that South Africa can enhance itself in terms of providing a comprehensive regulatory framework and position itself as an ideal seat of arbitration in Africa.

- Description: In the history of international relations, the adoption of the R2P principle in 2005 was widely understood to be a break-through in the international community’s efforts to respond to massive human rights violations and atrocities. Despite this, the international community’s implementation of the R2P has been widely contested, including in relation to its application in Sudan and Libya. There is agreement in the literature that, in both cases, the implementation of the R2P failed to achieve its intended purpose of protecting civilian populations. This thesis addresses the question of why the R2P failed in Sudan and Libya. Most explanations concerning the failure of the R2P in Sudan and Libya tend to focus on the politics of big power countries. The study argues that the failure to implement the R2P is related to the interactions between regional organisations and the international community (global organisations like UN) in attempting to solve large-scale human rights violent conflict. The study is firmly embedded in scholarly debates about humanitarian intervention so as to demonstrate the fact that this study is part of efforts to advance knowledge of scholarly debates on humanitarian intervention in this contemporary world order. The study combines a case study approach and qualitative research approach to achieve a nuanced understanding of the reason why the R2P failed in Sudan and Libya. The study relied on the use of documentary reviews and in-depth interviews of experts to collect data which was analysed using critical discourse analysis. The thesis demonstrated that the implementation of the R2P was characterised by a breakdown of the relationship between regional actors like the AU and global institutions like the UN. This breakdown contributed to the failure of the R2P in Sudan and Libya. The lack of financial and operational capacity for rapid deployment, the internal divisions with the AU, and the lack of political will within the AU members states were also cited as obstacles to the realisation of the R2P efforts in Sudan. To establish in-depth knowledge the study revealed other factors related to the politics of big power countries and how they played a part in the failure of the R2P in Sudan and Libya. Among these factors include implementation inconsistencies, the ICC factor, the absence of UNSC consensus in the response over Darfur and Libya, and the veto power factor and its implications in the efforts of the international community in both cases. This study also showed that the implementation of the R2P may not work effectively if left only to international actors to implement. Regional and sub-regional actors are important stakeholders of the R2P, and their interactions with the international community in actualising the implmementation of the R2P on the ground are essential. The manner in which the R2P was applied in Sudan and Libya is an indication its implementation requires improved interaction between regional actors and the international community at all level of collaboration including at global, regional and sub-regional level. This can build a strong foundation to drive the effective implementation of the R2P in future interventions. The findings of this thesis will significantly improve the available literature on the reason why the R2P failed in Sudan and Libya, particularly by paying much attention to the role of regional and sub-regional actors.

- Description: Three species of Nassella have naturalized in South Africa. Nassella trichotoma and N. tenuissima are declared weeds under category 1b of the National Environmental Management: Biodiversity Act (NEM:BA) and occur mainly in the montane grasslands of the Western and Eastern Cape provinces. Nassella neesiana is not listed in NEM:BA but is naturalized in the Eastern Cape, Western Cape and Free State provinces. Research conducted in the 1970s and 1980s led to vigorous government-funded awareness and control campaigns which ended in 2000. No research on Nassella distribution or control has been undertaken since then. Despite this hiatus, Nassella remains a dangerous genus in southern Africa, given the serious impacts of these species in similar social-ecological systems in Australia and New Zealand. This paper presents a synthesis of available information about Nassella invasions in South Africa and identifies research gaps. It specifically addresses these questions: What identification issues exist? What is the current spatial distribution of Nassella? What is the autecology of the genus? What are the social-ecological impacts of Nassella? What control measures are currently applied and what are their strengths and limitations? What do we know about Nassella distribution and its response to climate change? This paper highlights many knowledge gaps about Nassella, such as the species’ current distribution range, field identification and detection difficulties, and the uncoordinated control efforts that require urgent research to inform an effective management response.

No research on Nassella distribution or control has been undertaken since then. Despite this hiatus, Nassella remains a dangerous genus in southern Africa, given the serious impacts of these species in similar social-ecological systems in Australia and New Zealand. This paper presents a synthesis of available information about Nassella invasions in South Africa and identifies research gaps. It specifically addresses these questions: What identification issues exist? What is the current spatial distribution of Nassella? What is the autecology of the genus? What are the social-ecological impacts of Nassella? What control measures are currently applied and what are their strengths and limitations? What do we know about Nassella distribution and its response to climate change? This paper highlights many knowledge gaps about Nassella, such as the species’ current distribution range, field identification and detection difficulties, and the uncoordinated control efforts that require urgent research to inform an effective management response.

- Description: Uncertainty as to the future of the liberal international order and the position of the United States within an international system in which it is not the hegemon remains a topic of debate amongst scholars of International Relations (Acharya: 2017; Duncombe and Dunne: 2018; Ikenberry: 2009, 2011, 2014; Nye: 2012 and Monteiro: 2011/2012). Fukuyama’s (1989: 4) “end of history” has not happened and a resurgence of populist leaders within established liberal democratic countries has contributed to a rapid decline of moral and ethical leadership and has further compromised the future of the liberal international order (Duncombe and Dunne, 2018: 27). As the relative power of the United States declines and the future of the liberal international order becomes increasingly uncertain, support for its future must be sought from outside the West (Duncombe and Dunne, 2018: 25 and Ikenberry: 2009). This thesis seeks to locate where potential non-Western support for the future liberal international order may be found. It does so through an analysis of how Islamic states who are part of the Organisation of Islamic Cooperation vote on the United Nations Human Rights Council (UNHRC). The OIC has a significant presence at the UNHRC and can influence the direction of the liberal international human rights regime. The evidence examined in this research project suggests that the future liberal international order and human rights regime can indeed expect some form of cooperation from the OIC. However, the OIC, and by extension Islamic states, would likely offer more support at least for human rights, if a more common understanding were to be found.

The jackal as a mesopredator : dietary response to an apex predator and role as an endozoochore

- Description: Interactions between apex predators, mesopredators and their impacts on trophic dynamics have been well documented. However, the influence of apex predators, through the provision of carrion, on the foraging ecology of African mesopredators is poorly understood. To investigate such resource supplementation by apex predators for mesopredators, the black-backed jackal Canis mesomelas, a generalist mesopredator, was used as a model species to improve our understanding of this topic in South African ecosystems. To do this, I compared the diet of jackal at replicated sites with and without cheetah in the eastern Karoo, South Africa. Scat samples were macroscopically categorized into six broad dietary categories: mammal, reptile, bird, fruit, forage and insect. Mammalian prey was further identified to species and grouped into six functional dietary categories: carnivore, large ungulate, small ungulate, small mammal, and unknown mammal. Jackal diets were dominated by mammal prey, with significant differences in the biomass and frequency of occurrence of mammals by jackal at sites with cheetah and without cheetah. Mammal consumption, showed limited variation amongst seasons. Resource supplementation provided by predator derived carrion is an important factor influencing jackal foraging ecology. The emergent hypothesis that jackal may show demographic responses (increased fecundity, survival, density) to this supplementation needs to be tested. This study also provided an opportunity to investigate the potential role of jackal as an endozoochore. Jackal consume fruits and their seeds, yet to our knowledge, an investigation into their seed dispersing abilities is yet to be investigated. This study assessed the viability and germination capacity of ingested seeds extracted from jackal scat samples using the tetrazolium tests and germination trials. Seed viability and germination of all three species (Grewia occidentalis, Pappea capensis and Diospyros lycioides) were significantly lower than uningested seeds. These results suggest that jackal gut passage is acting severely on ingested seeds. This study represents a novel investigation into differences in jackal diet in sites with and without cheetah as well as the role jackal play in endozoochory, contributing to improved understanding of the ecological role of jackal.

- Description: Transformational leadership (TFL) is a leadership theory that describes how leaders create change through their ability to inspire and motivate followers toward self-improvement and innovation that benefits the individual, the group, and the organisation as a whole.This psychobiographical research study explored the leadership style of Richard Branson by using Bass’s theory of transformational leadership. An exploratory-descriptive design was utilised to examine Branson’s life history. He was selected for the study through non-probability purposive sampling based on his history as an extraordinary leader and entrepreneur. Primary and secondary sources of historical and biographical data were used in the data collection process. The data was then processed using thematic analysis against the theoretical framework of transformational leadership. From an ethical perspective, the researcher took care to avoid the misrepresentation of the subject, thus balancing objective research with respect for the psychobiographical content and minimising the risk of doing harm. The findings demonstrated that Branson’s leadership style consists of, and corresponds to a large extent, to the four components of TFL.

- Description: This study seeks to determine the legality and enforceability of an automatic termination clause in a contract of employment. Our law seems to have two different procedures in dealing with this issue. The first aspect is to determine whether the automatic termination clause is inserted in a contract of employment merely to circumvent the provisions of the Labour Relations Act (LRA), in particular section 5(2)(b) of the LRA. If the intention is found to be to circumvent the purpose of the said provisions of the Act, then an automatic termination clause is not allowed and any termination of the contract resulting therefrom becomes a dismissal challengeable at the CCMA, Bargaining Council or Labour Court depending on the issue at hand. In the alternative, there is no dismissal for the purposes of section 186(1) of the Act in circumstances where the end of an agreed fixed term is defined by the occurrence of a particular event. Put differently, there is no dismissal when the agreed and anticipated event materialises. The Constitution of the Republic of South Africa provides that everyone has the right to fair labour practices. This provision guarantees the right not to be unfairly dismissed and is in line with Article 4 of Convention 158 of the International Labour Organisation which provides that the employment of a worker shall not be terminated unless there is a valid reason for such termination connected with the capacity or conduct of the worker or based on operational requirements of the undertaking, establishment or service. This study aims to investigate the question of the legality and enforceability of an automatic termination clause in a contract of employment by analysing inter alia, the Constitution, LRA, ILO recommendations and the authorities in order to determine the extent of protection afforded to employees against employers.

- Description: Research on African women and HIV, particularly research that investigates their experiences of living with the virus, has been relatively peripheral. As a response to the apparent knowledge and research gaps, this project is a qualitative study involving women living with human immunodeficiency virus (WLHIV) and attending an anti-retroviral treatment (ART) clinic at Zomba Central Hospital in Southern Malawi. The study utilised an interpretative phenomenological analysis (IPA) approach, which informed all aspects of the data-collection and data-analysis processes. Using purposive sampling, 12 women were recruited and interviewed on three occasions over a period of six months. The interviews were conducted in Chichewa and audio recorded and later transcribed into English. Fourteen superordinate themes emerged from the analysis representing the women’s prominent life experiences, how they received their diagnosis, and how they contained the trauma of their diagnosis. The analysis also developed themes regarding how they coped with the challenges of living with the human immunodeficiency virus (HIV) and made sense of their experiences. The results showed that the women struggled with multiple challenges experienced through their various identities as WLHIV. The findings also pointed to interlocking disadvantages that put the women at risk of infection, and which were present from childhood. This has implications for more structural and multidisciplinary interventions for WLHIV.

- Description: First-generation African students contend with psychosocial, structural, educational background and financial struggles to gain access to university. The first-generation students exercised their available resources and power, agency and acquired skills to negotiate their journey and entrance to university. They had to figure out for themselves how to navigate a daunting and complex path to university without relying on the knowledge and informative engagement with previous older familial generations who had the experience of attending university. They are a testimony of a generation of young people who have the resilience and grit to compensate for the structural deficits they have and experienced through their disadvantaged educational systems and their financially disadvantaged backgrounds. Although one would expect that teachers would automatically be the first encounter a high school student has of acquiring information on how to gain access to university, many of the previously disadvantaged school teachers are simply too inundated with work to be able to facilitate this process. First-generation students found themselves mostly having to look beyond the parameters of the classroom to acquire these resources. Following a qualitative approach of narrative enquiry, five African students with life experience of being first-generation Rhodes University students whose mothers were or are domestic workers, narrated their personal stories. A first-generation student’s agency, negotiation and navigation through obstacles, struggles and setbacks in the backdrop of having mothers who were/are domestic workers who socialised their children in a specific ideology to value and pursue education are the foundations for this narrative enquiry. This research provides a framework for investigating the concept of adequate and appropriate university preparedness to address the inadequate resources that previously disadvantaged schools have in terms of preparing their students to compete (in often times with more advantaged students) to gain access to university. These first-generation students did not come from educational environments where career counselling or aptitude tests are done to better equip them for entrance into university and appropriate subject and degree choice. Several common traits emerged that give perspective to the narrative of the journey that first-generation students’ had to endure and overcome to gain access to university.

- Description: Reintroduced lion (Panthera leo) populations pose several ecological and management challenges in small (< 1,000 km2), fenced wildlife reserves. Changes in the natural socialecological conditions of reintroduced lion populations may lead to rapid population growth and a breakdown of natural predator-prey relationships. Reduced competition with other lions also likely reduces the potential for reintroduced lions to naturally form groups. My study used a combination of questionnaire surveys with tourists, existing lion demographic data from 16 wildlife reserves across South Africa and a controlled lion social experiment to address these ecological and management issues. Tourism was the primary reason for lion reintroductions. Tourists scored lions highly in terms of preference for viewing on safari, in particular, lions in larger, natural groups and adult males. Viewing lions also enhanced a tourists’ overall safari experience. The breakdown of natural social behaviour may likely therefore reduce tourist satisfaction related to lions. The number of resident prides and male coalitions in a reserve affected lion vital rates. Lion population growth rate was highest in reserves that contained a single resident pride, and the presence of unknown adult males significantly reduced cub survival and lioness birth intervals. The ratio of male cubs born also increased in reserves with a higher density of unknown adult males. Fertility control measures (deslorelin implants and unilateral hysterectomy) were effective at limiting lion population growth. Deslorelin treatment increased the age of first reproduction or the birth interval and decreased the subsequent litter size of treated lionesses to closer reflect natural vital rates in larger (> 10, 000 km2) systems. However, there was variability in infertility response between lionesses including adverse reactions in a small proportion of treated individuals. The number of resident prides and male coalitions in a reserve affected lion social behaviour. Lionesses formed larger groups in reserves with a higher density of unknown adult female neighbours, likely driven by territory defence. Lion prides with resident cubs were generally more fragmented, likely in response to reduced competition from unknown adult males. However, in areas with a high density of unknown adult female neighbours, prides with cubs formed larger groups likely in response to heightened territory defence. Therefore, with smaller foraging group sizes, predation rate was increased in reserves with reduced competition from unknown lions. My study supports a metapopulation approach for the management of lions in small, fenced reserves, and the standardisation of lion management procedures and database management. Endorsed by the Biodiversity Management Plan for lions in South Africa, this will enhance the long-term conservation potential of isolated populations.

- Description: Reintroduced lion (Panthera leo) populations pose several ecological and management challenges in small (< 1,000 km2), fenced wildlife reserves. Changes in the natural socialecological conditions of reintroduced lion populations may lead to rapid population growth and a breakdown of natural predator-prey relationships. Reduced competition with other lions also likely reduces the potential for reintroduced lions to naturally form groups. My study used a combination of questionnaire surveys with tourists, existing lion demographic data from 16 wildlife reserves across South Africa and a controlled lion social experiment to address these ecological and management issues. Tourism was the primary reason for lion reintroductions. Tourists scored lions highly in terms of preference for viewing on safari, in particular, lions in larger, natural groups and adult males. Viewing lions also enhanced a tourists’ overall safari experience. The breakdown of natural social behaviour may likely therefore reduce tourist satisfaction related to lions. The number of resident prides and male coalitions in a reserve affected lion vital rates. Lion population growth rate was highest in reserves that contained a single resident pride, and the presence of unknown adult males significantly reduced cub survival and lioness birth intervals. The ratio of male cubs born also increased in reserves with a higher density of unknown adult males. Fertility control measures (deslorelin implants and unilateral hysterectomy) were effective at limiting lion population growth. Deslorelin treatment increased the age of first reproduction or the birth interval and decreased the subsequent litter size of treated lionesses to closer reflect natural vital rates in larger (> 10, 000 km2) systems. However, there was variability in infertility response between lionesses including adverse reactions in a small proportion of treated individuals. The number of resident prides and male coalitions in a reserve affected lion social behaviour. Lionesses formed larger groups in reserves with a higher density of unknown adult female neighbours, likely driven by territory defence. Lion prides with resident cubs were generally more fragmented, likely in response to reduced competition from unknown adult males. However, in areas with a high density of unknown adult female neighbours, prides with cubs formed larger groups likely in response to heightened territory defence. Therefore, with smaller foraging group sizes, predation rate was increased in reserves with reduced competition from unknown lions. My study supports a metapopulation approach for the management of lions in small, fenced reserves, and the standardisation of lion management procedures and database management. Endorsed by the Biodiversity Management Plan for lions in South Africa, this will enhance the long-term conservation potential of isolated populations.

- Description: Hip-hop is frequently linked to misogyny and other forms of violence. This link, in many instances, is often presented outside of a critical understanding of complex underlying societal and gender dynamics. South Africa’s high rates of violence against women make it necessary to understand how hip-hop videos interact with society, as hip-hop, in its commercial form, has become a growing music genre in South Africa. Rhodes University, which has a notable student following of hip-hop, has experienced concerning levels of gender-based tensions as evidenced by the rise of the “fallist” movement’s #RapeCultureMustFall, #RUReferenceList and the suicide of Khensani Maseko, at the instigation of an alleged incident of rape, perpetrated by her boyfriend and fellow student. It is therefore of interest to investigate how a select group of Rhodes University student-fans of hip-hop make meaning out of selected South African commercial hip-hop music videos. The hip-hop music videos chosen for the study, hence Pitbull Terrier (Die Antwoord), Pearl Thusi (Emtee), Dlala ka yona (L’Tido), All eyes on me (AKA featuring Burna Boy, Da L.E.S and JR) and Ragga Ragga (Gemini Major featuring Casper Nyovest, Riky Rick and Nadia Nakai), were selected on the strength of their popularity and uniquely gendered scenarios. This study draws on qualitative research methods, thus qualitative thematic content analysis, focus group and in-depth interviews. The study establishes that despite gender being a contentious issue at Rhodes University, students make meaning out of the gendered portrayals based on their own experiences, socialisation, cultural values and level of submission to the discourse of hip-hop. This study seeks to understand how selected student-fans of hip-hop read the gendered portrayals of the music videos, based on their own experiences, socialisation, cultural values, and level of submission to the discourse of hip-hop.

- Description: Financial literacy concerns the understanding of those concepts related to finances. Financial literacy is globally recognised as an essential life skill since people must be able to differentiate among a wide range of products, services and providers of financial products to manage their finances successfully. Individuals make daily financial decisions about expenditures and savings. In environments where resources are scarce poor financial decisions have high impact on the quality of life and future access to resources. People are not adequately educated with regards to finance and wealth creation, save too little for retirement, overspend and tend to purchase items that are not prioritised for the household. Due to limited empirical research, it is clear that new research into the effect of financial literacy on the relationship between financial behaviour and financial well-being on budget intentions is required. This study was anchored to two theories, namely the Theory of Planned Behavior (TPB), intended to explain all behaviors in which people have the ability to exert self-control and the Trans-Theoretical Model of Behaviour Change (TTM) that could be used to change people’s financial behaviour. The problem being explored is that the mismanagement of funding for beneficiaries at higher education institutions. NSFAS has begun to increasingly make cash payouts available to beneficiaries yet there is not enough empirical evidence to suggest that the beneficiaries possess adequate personal finance management skills or they are financially literate to being able to better manage their finances. When the beneficiaries are not adequately skilled regarding personal finance management skills, they could misuse such funds and this could result in these beneficiaries failing to complete their studies. This study contributed to the identified knowledge gap by investigating the mediating effect of financial literacy on the relationship between financial behaviour and financial well-being on budget intentions among South African university students. This study included quantitative research methods and questionnaires were used as the primary means of collecting the data. The sample included 204 participants from the University of Fort Hare. The final sample yielded a total response rate of 81.6%. A cross sectional research design was used for this study. Convenience sampling was used in this study. The researcher made use of student leaders to distribute and collect questionnaires. This study included 14 hypotheses. The dependent variables included Budget Intentions and Financial Literacy. The independent variables included Financial Well-being and Financial Behaviour. Self-control as a financial behaviour predicted university students’ budget intentions. Individuals with better self-control were more likely to forgo indulgences and focus on the long-term goals, thereby sticking to a budget. Optimism significantly predicted budget intentions of university learners. People who tend to engage in deliberate thinking more often are more likely to better manage their personal finances through budgeting. Individuals who have more positive financial attitude were more satisfied with their financial situation implying that they undertake planning and budgeting as far as finance issues are concerned. Financial socialisation from a parental perspective significantly influenced university students’ financial behaviour, namely, financial teaching, monitoring and modelling. People with better self-control are more likely to practise saving in almost every income flowing to them. Financial behaviour, particularly, deliberating thinking significantly predicted financial literacy. Positive financial behaviours such as being financial literate such as a reduction in day-to-day expenses were found to be associated with lower financial anxiety levels. Financial behaviours including positive financial attitude significantly predicted financial literacy. Individuals who had their financial issues monitored by parents for the purpose of earning advice and tips on financial matters were positively behaving pointing to the notion that they were financial literate and knowledgeable. The implication of the study is that management of institutions of higher learning should encourage students to practise self-control behaviour regarding their finances in order to improve budget intentions. It is also recommended that the Universities management should design short courses where students can be trained on or made aware of the importance of self-control as much as good financial behaviour is concerned.

- Description: A positively charged phthalocyanine (2,9,16,23-tetrakis[4-(N-methylpyridyloxy)]-phthalocyanine (ZnTPPcQ)) was non-covalently linked to carbon based nanoparticles: detonation nanodiamonds (DNDs), carbon dots (CDs) and graphene quantum dots (GQDs) to form nanosembles of DNDs-ZnTPPcQ, GQDs-ZnTPPcQ and CDs-ZnTPPcQ, respectively. Irrespective of its small size and the least number of Pcs (41.67 μg loading per milligram of DNDs), DNDs-ZnTPPcQ gave the highest singlet oxygen quantum yield (0.62) in dimethyl sulfoxide compared to the rest of the conjugates. This resulted in superior PDT activity against MCF7 breast cancer lines, with the lowest cell viability of 28% compared to ZnTPPcQ-CDs and ZnTPPcQ-GQDs at 30.1 ± 0.02% and 31.4 ± 0.23%, respectively.
